No.14/876147, filed on Oct. 6, 2015, for which priority is claimed under 35U.S.C. § 120; and this application claims priority of application Ser.No. 104204338 filed in Taiwan on Mar. 23, 2015 under 35 U.S.C. § 119,the entire contents of all of which are hereby incorporated byreference.

Description of the Prior Art

According to the prior art, a traditional heating appliance, as depictedin FIG. 1, primarily comprises a cylinder 10, heating pipes 11, a waterinlet pipe 12, and a water outlet pipe 13. The water inlet pipe 12 andthe water outlet pipe 13 are located at the bottom portion of thecylinder 10 for channeling water, and the heating pipes 11 are alsoinstalled at the bottom portion of the cylinder 10 to heat the waterinside the cylinder 10. The interior of the cylinder 10 is provided witha circular partition 14, and the heating pipes 11 and the water outletpipe 13 are disposed within the circular partition 14. The upper portionof the circular partition 14 is provided with an inner top panel 15, andthe water outlet pipe 13 upwardly passes through the inner top panel 15and outward therefrom, thereby enabling the water inlet pipe 12 tochannel water to the periphery of the circular partition 14. Inaddition, the inner top panel 15 is provided with a circulation opening16.

When water is channeled from the water inlet pipe 12 to the periphery ofthe circular partition 14, the water gradually overflows to the heatingpipes 11, whereupon the heating pipes 11 raise the temperature of thewater within the circular partition 14. (the interior of the circularpartition 14 is a heating area 110). The heated water rises to the innertop panel 15 at the upper portion of the heating area 110, and thenoverflows into the water outlet pipe 13 through the circulation opening16, thereby enabling the heated water to flow out from the water outletpipe 13. Using such a method, water is continually channeled to theperiphery of the circular partition 14, and then heated within thecircular partition 14, after which heated water flows out from the wateroutlet pipe 13.

However, because heating of the cylinder 10 is incomplete, with only thewater within the circular partition 14 being heated, thus, a smallamount of water can be quickly heated for use by the user, and avoidsheating the entire cylinder 10, thereby remedying the shortcomings ofwasting energy resources and time consumption while waiting for hotwater.

Although the heating area 110 of the heating appliance of the prior artis centered on the water within the circular partition 14, however,because the circular partition 14 is only a metal plate, and after thewater within the circular partition 14 is heated, heat is stilltransferred to the water exterior to the circular partition 14 throughthe circular partition 14. Furthermore, the unheated water around theperiphery of the circular partition 14 also cools down the circularpartition 14, thus causing the heating pipes 11 to expend even moreenergy. And these shortcomings are the major drawbacks in the design ofthis type of heating appliance of the prior art.

Referring to FIG. 2, which depicts a second type of heating appliance ofthe prior art, primarily comprising a cylinder 20, a heating pipe 21, awater inlet pipe 22, and a water outlet pipe 23. The interior of thecylinder 20 is provided with a partition 24, a heating area 240 isprovided within the partition 24, and the heating pipe 21 is locatedwithin the heating area 240. An upper portion of the heating area 240 isprovided with a water outlet pipe 23, which channels out water to theexterior of the cylinder 20. The water inlet pipe 22 channels water fromthe cylinder 20 to the exterior of the heating area 240, with thepartition 24 being provided with a circulation opening 25.

When water is channeled into the interior of the cylinder 20 from thewater inlet pipe 22, the water enters the heating area 240 through thecirculation opening 25 of the partition 24, whereupon the heating pipe21 raises the temperature of the water within the heating area 240. Theheated water then rises and overflows into the water outlet pipe 23,thereby enabling heated water to flow out from the water outlet pipe 23.Using such a method, water is continually channeled into the interior ofthe cylinder 20, and the heating pipe 21 raises the temperature of thewater within the heating area 240, after which the heated water flowsout from the water outlet pipe 23.

Although the second type of heating appliance of the prior artconcentrates the heat on the water within the heating area 240, however,the partition 24 is only a single metal plate, and after heating thewater within the partition 24, heat is still transferred to the waterexterior of the partition 24 through the partition 24. Furthermore, theunheated water exterior of the partition 24 also cools down thepartition 24, causing the heating pipe 21 to expend even more energy.And these shortcomings are the major drawbacks of this second type ofheating appliance of the prior art.

Accordingly, both in the first type of heating appliance of the priorart and the second type of heating appliance of the prior art, only ametal plate is used as the partition 14 (24) for the heating area,making it impossible to truly retain stored heat, but instead transfersthe heat energy to a cold water area, where the heat energy isdissipated, thereby causing the heating pipe to expend even more energy.

U.S. Pat. No. 1,653,672 discloses that a heat-isolating tubular memberin which a heating member is inserted is communicated with the waterstorage area through additional channeling pipes which are partiallyexposed to exterior of the water storage area, and thus it iscomplicated in structure, and the heated water can be cooled so that itis energy-consuming.

The present invention intends to provide an improved ceiling fan thatimproves the shortcomings mentioned above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 3, which depicts the first embodiment of a heatingappliance structure of the present invention comprising a cylinder 30, aheating pipe 31, a water inlet pipe 32, a water outlet pipe 33, a waterstorage area 34, and a heating area 35. The cylinder 30 is able to storewater, and the interior of the cylinder 30 is partitioned into theheating area 35 and the water storage area 34. The heating pipe 31extends into the heating area 35 of the cylinder 30, the water inletpipe 32 channels water into the water storage area 34 within thecylinder 30 from the exterior thereof, and the water outlet pipe 33channels out heated water from the cylinder 30 to the exterior of thecylinder 30 using the water outlet pipe 33. The heating area 35 isprovided with the heating pipe 31 for conducting heat thereto, and anupper portion of the heating area 35 is provided with a heat flowconduit 38, which extends to the water outlet pipe 33 for channeling outheated water to the exterior of the cylinder 30. The water inlet pipe 32channels water into the heating area 35 from the cylinder 30, and theheating area 35 is formed by being partitioned off from the waterstorage area 34 using a thermal insulation space 36. The thermalinsulation space 36 is provided with at least one partition 361, and aninterspace formed at a preset distance between the heating area 35 andthe water storage area 34 is defined as the thermal insulation space 36.The interior of the thermal insulation space 36 can be an air layer, orthe interior of the thermal insulation space 36 is a vacuum layer, orthe interior of the thermal insulation space 36 is disposed with thermalinsulation material. The thermal insulation space 36 is provided with acold flow conduit 37, which enables water in the water storage area 34to be channeled into the heating area 35. The heat flow conduit 38 isfitted to the thermal insulation space 36, and the heat flow conduit 38extends to close to the water outlet pipe 33 to enable hot water to riseto the water outlet pipe 33, where the hot water is expelled.

According to the aforementioned structure, in the heating appliancestructure of the present invention, the water source is channeled intothe interior of the cylinder 30 through the water inlet pipe 32, andenters the water storage area 34 of the cylinder 30. The water thenflows into the heating area 35 from the water storage area 34 throughthe cold flow conduit 37, whereupon the heating pipe 31 raises thetemperature of the water within the heating area 35. Based on the risingheat principle, the heated water then rises and overflows into the waterstorage area 34 through the heat flow conduit 38, and the heated waterflows out through the water outlet pipe 33. Using such a method, wateris continually channeled into the interior of the cylinder 30, theheating pipe 31 raises the temperature of the water within the heatingarea 35, and the heated water flows out from the water outlet pipe 33.

Because the thermal insulation space 36 is an interspace, thus, it isable to effectively block the transmission of heat energy. Accordingly,the thermal insulation space 36 blocks heat energy from dissipating tothe water storage area 34. Furthermore, the thermal insulation space 36prevents the low temperature of cold water in the water storage area 34from being transmitted to the heating area 35, thereby enabling theheating area 35 to store heat energy while preventing it fromdissipating. Hence, the heating appliance structure of the presentinvention achieves the function of reliably providing the thermalinsulated heating area 35 and the water storage area 34, and does awaywith the method of only using a metal plate to serve as a thermalinsulation structure of the prior art.

Referring to FIGS. 4-6, in this embodiment, the heating appliancestructure further includes a heat-isolating portion 40. At least one endof the heat-isolating portion 40 is connected to the cylinder 41, theheat-isolating portion 40 extends laterally inward, and theheat-isolating portion 40 itself bends concavedly and defines theheating area 42. The heating area 42 has an opening 43 in the waterstorage area 44. The heat-isolating portion 40 is entirely surrounded byand entirely located within the water storage area 44. Theheat-isolating portion 40 and the cylinder 41 form at least one gap 45therebetween, and the at least one gap 45 is part of the water storagearea 44 and directly communicating with the heating area 42. The heatingpipe 46 extends into the heating area 42 and is located entirely withinthe heating area 42. The heat-isolating portion 40 is substantiallyC-shaped (smooth or transitional). The opening 43 of the heating area 42faces downwardly. The heat-isolating portion 40 arcuately extends forlarger than 80 degrees. In this embodiment, the heat-isolating portion40 arcuately extends around the heating pipe 46 for larger than 180degrees relative to the heating pipe 46. The heat-isolating portion 40bends transitionally and has two transitional corner portions 47, and adistance D between the heat-isolating portion 40 and the heating pipe 46is smaller than a radial size of the heating pipe 46. The water inletpipe 48 does not protrude into the water storage area 44, and the wateroutlet pipe 49 does not protrude into the water storage area 44. Theheat flow conduit 50 is uprightly connected to the heat-isolatingportion 40 and communicates with the heating area 42, wherein along alongitudinal direction the heat flow conduit 50 does not overlap theheating pipe 46. In other embodiment, the heat-isolating portion 40 amay be hollow (as shown in FIG. 7-9).
